Patent CA-2244342-A1 (CA)
Inventor: SCOTT HUGH D
IPC: E21B49/00
Filed: 1998-07-29
Abstract: The present invention provides for method and an apparatus for determining the porosity of a geological formation surrounding a cased well. The method further comprises of generating neutron pulses that release neutrons into an area adjacent the well, from a neutron source. Neutrons are sensed and a plurality of neutron detector count rates is acquired using at least two neutron source to neutron detector spacings. A timing measurement is acquired at one of the spacings to measure a first depth of investigation. A ratio of the neutron detector count rates is acquired to measure a second depth of investigation. An apparent porosity is calculated using the timing measurements and the ratios of neutron count rates. The effect of a well casing on the calculated apparent porosity is determined in response to at least one of the ratio of neutron detector count rates and the timing measurement. A cement annulus is computed based on the ratios of neutron count rates and the timing measurement. A formation porosity is calculated by performing a correction to the apparent porosity for the casing and the cement annulus.

Patent CA-2249455-A1 (CA)
Inventor: SUESS GABRIELE MARIA
IPC: A61K38/00
Filed: 1997-03-26
Abstract: The invention is directed to growth factors or precursors of catalytic antibodies comprising a B-cell surface molecule binding portion, which can induce B-cell mitogenesis. The preferred B-cell surface molecule binding portions are the immunoglobulin binding molecules of protein L from peptostreptococcus magnus, protein A, protein G and protein H. The growth factor having an ability to induce B-cell mitogenesis can be further linked to a target antigen to which catalytic antibodies are sought. B-cell mitogenesis is then dependent on the catalytic cleavage of the antigen portion of the growth factor by catalytic antibodies on the surface of B cells. The method of the present invention is useful for generating catalytic antibodies for both therapeutic and diagnostic purposes.

Inventor: GILLBERRY WILFRED A
IPC: G01D5/39
Filed: 1997-09-22
Abstract: A system for remote meter viewing and reporting. The system comprises a remote camera located at the meter. The remote camera is coupled to a central computer through a communications channel. In response to a command from the central computer, the camera scans the meter face, i.e. readings on the dials, and stores an image in memory. The scanned image is transmitted to the central computer. The central computer includes software for analyzing the scanned image in determining the consumption of electricity, for example, by comparing the current readings on the dials with the readings on the dials taken at the last billing cycle. The processed image is then used to generate a billing statement which is sent to the household consumer using conventional post. In another aspect, the billing statement generated by the system includes scanned images of the past and current meter readings. The system according to the present invention is suitable for public utilities, such as gas, electricity, water companies and leasing companies which lease office equipment to companies situated in remote locations, which equipment is fitted with meters which record their use, i.e. copying machines, printers, etc. where it is desirable to determine the quantities of copies made, thus enabling the timely scheduling of visits of company service representatives to perform ongoing maintenance, thereby helping to ensure minimal down-time and optimal equipment performance.

Title: Multichamber container with expanded interior walls
Inventor: CONNAN PATRICK ANDRE
IPC: B29C49/12
Filed: 1997-12-19
Abstract: Multichamber tubular containers (50) are made by extrusion or injection stretch blow molding. The containers usually will have two or three chambers and one or more web walls (42). The web walls are relatively rigid as formed. The web walls (42) must be stretched laterally to increase their flexibility which is needed for the uniform dispensing of product from the tubular chambers. The webs (42) can be stretched mechanically by the rotation of rods (46), such as stretch rods, or pneumatically by a differential gas pressure in the chambers while the webs (42) are at or near the glass transition temperature and can flow. The web walls for a circular tubular container can be stretched up to about one-half the diameter of the tubular container.

Abstract: L'invention concerne un procédé de formation d'un polymère ramifié qui consiste à former plusieurs chaînes de polymères linéaires croissantes par polymérisation d'un monomère protégé contre la ramification et formant une groupe d'extrémité réactif qui, dans un premier état, est électrophile ou nucléophile; à exposer les chaînes de polymère linéaires croissantes à un agent de transfert de chaîne pour pousser le groupe d'extrémité réactif d'au moins une première chaîne de polymères linéaires croissantes à inverser son caractère électrophile ou nucléophile; ainsi, un groupe d'extrémité réactif non inversé dans une deuxième chaîne de polymères linéaires croissantes entre en réaction avec le groupe d'extrémité réactif inversé dans la première chaîne de polymères linéaires croissantes pour créer un polymère ramifié, et remet le caractère électrophile ou nucléophile du groupe d'extrémité réactif inversé dans son premier état, et ainsi il peut continuer à ajouter des monomères de manière linéaire; le procédé consiste également à fixer la polymérisation par ajout d'un composé possédant plusieurs sites réactifs capables de réagir avec les groupes d'extrémité réactifs des chaînes de polymères lorsqu'ils sont dans leur premier état. Le procédé permet de préparer des polymères dendritiques à poids moléculaire ultra élevé dans lesquels les joints de ramification sont assemblés sur place (c'est-à-dire sont à ramification autonome) de manière convergente pendant la polymérisation des monomères.

Patent CA-2287499-A1 (CA)
Inventor: COUSINS LISA
IPC: B01D59/44
Filed: 1998-04-22
Abstract: An RF-only quadrupole mass spectrometer in which an auxiliary RF field (dipole or quadrupole) excites selected ions at low q (typically between 0.20 and 0.89). The excited ions experience radial excursions, but many do not experience excursions sufficient to strike the rods, and are therefore transmitted and acquire increased kinetic energy in the fringing fields at the exit ends of the rods. The excited ions may therefore be selected from the non-excited ions either by their increased axial kinetic energy, or by their radial dispersion, or both, and are detected for analysis, producing sharp peaks of high sensitivity at low q, while retaining the high acceptance and other advantages of RF-only mass spectrometers. Operated in converse fashion, a high quality notch filter can be achieved. In the notch filter, an auxiliary RF field again excites ions and notches some of them out by causing them to strike the rods. Ions which are not notched out but which are nevertheless excited by the auxiliary field are discriminated against, again either by reason of their higher axial kinetic energy or their spatial dispersion or both, so that only ions on axis are detected, producing a high resolution high sensitivity notch filter.
